The present invention relates to a memory card capable of automatically correcting a kind of interface standard. More specifically, it is possible to automatically correct a connection standard between the communication interface and the read / write device by extending one communication interface in addition to the standard interface. It relates to a memory card equipped with a function.

There are many kinds of small memory cards known on the market at present. For example, the common requirements and features of small memory cards such as SD, CF, SM, MMC, xD, MS, etc. are to reduce the volume as much as possible and to expand the capacity as much as possible. Is reaching. Although memory cards have made significant improvements in capacity, every memory card can only be connected to a read / write device, such as a computer or an electronic device, in principle, according to its own standard standards. To do this, you must use the same card reader, and you cannot connect directly to a computer.

In order to solve the above problem, the industry has attempted to develop a memory card having two connection interfaces, so that one of the interfaces is simply connected to the computer through a switching module that matches the appearance type of the interface. . This method effectively solved the problem of not being able to connect the memory card directly to the computer. The more advanced idea, however, is to connect the memory card directly to the computer's interface port, which significantly improves the convenience of use, that is, by adding one interface port directly to the memory card. Plug the port directly into the interface connector on your computer. However, before realizing this idea, one must first consider the difference between the specification of the memory card itself and the standard of the interface currently used in computers.

The most common interface connector for computers today is USB (Universal Serial Bus), which allows direct connection with most computers if USB is installed on the memory card. However, it is important to consider that there is a difference between the specification between the memory card itself and the USB interface port, and to avoid being tied to the specification of the expansion interface, it may rather affect the normal use of the memory card-specific interface. For example, in FIG. 18, the USB interface jack 80 is disclosed, and the front end of the USB interface jack 80 is formed of a rectangular metal frame 81, and an insulating plate (inside the frame 81) is provided. 82 is provided, and four terminals 820 of the data lines D +, D-, the power lines VCC, and GND are provided on the insulating plate 82, respectively.

When the type of the USB interface is divided into male and female, the USB interface jack 80 is one male jack, and generally, the USB interface connector 90 (for example, as shown in FIG. 19) installed in the computer is one. In the female jack type, the USB interface connector 90 is provided with one insulating plate 92 at an upper portion of the rectangular metal housing 91, and is disposed between the upper surface of the insulating plate 92 and the upper surface of the inside of the housing 91. One gap is provided, and four groups of contact bullet pieces 920 are provided on the bottom surface of the insulating plate 92, and they respectively correspond to four terminals 820 on the USB interface jack 80, and also the housing 91. Four groups of stereotactic bullet pieces 910 protruding into the housing 91 are respectively installed at the upper ends of the lower stages to block the USB interface jack 80 fixedly inserted into the housing 91.

FIG. 20 shows the state after the USB interface jack 80 is inserted into the USB interface connector 90. The frame 81 of the USB interface jack 80 is inside the housing 91 of the USB interface connector 90. As shown in FIG. The insulating plate 82 in the frame 81 is inserted between the inner bottom surface of the housing 91 and the insulating plate 92, and the contact bullet piece 920 on the insulating plate 92 is inserted into the insulating plate 82. The electrical connection is made in electrical contact with the upper terminal 820.

As can be seen from the above description, referring to the USB interface jack 80, the action of the frame 81 is to fix the position, and what actually constitutes the electrical connection is the insulating plate 82 and the terminal 820 thereon. As an example, if one USB jack is integrated into the memory card in consideration of the basic dimensions, only the insulating plate 82 may be selected so that the terminal 820 is installed above and actually achieves the purpose of electrical connection. However, if only the structure that actually achieves the electrical purpose, the specification may still not match the existing memory card, for example, as shown in Figure 19, the housing 91 of the USB interface connector 90 The gap between the inner bottom surface and the insulating plate 92 thereon provides a space for inserting the insulating plate 82 of the USB interface jack 80, and the height of the space is slightly larger than the thickness of the insulating plate 82. Even if it is convenient to insert, the stereotactic bullet piece 910 should be installed separately to prevent it tightly. If the insulator plate 82 is to be incorporated in the memory card, its thickness must still match the gap between the inner bottom of the housing 91 and the insulator plate 92 above it, and if the thickness is insufficient, it will loosen and the electrical connection will be poor. There is a possibility. However, if already integrated into the memory card, only one side can not meet the specification requirements of the USB interface itself. Taking an SD card as an example, the width / length / width is 24 mm, 32 mm, and 2.1 mm in order, and the distance between the inner bottom surface of the housing 91 of the USB interface connector 90 and the insulating plate 92 thereon is about. 2.5mm. In other words, when the USB interface port taking only the electrical connection portion is integrated into the SD card so as to meet the standard of the SD card (ie, the thickness is 2.1 mm), in terms of thickness, the inside of the USB interface connector 90 There is not enough to reliably insert it into the USB interface standard.

In order to correct the difference in the specifications generated after incorporating the USB jack into the memory card, the inventor has already submitted the patent of the invention patent application No. 094109961, `` Memory card with interface standard correction function and its protective cover '', the specific solution Provided. The patent proposes to store a memory card in one protective cover, among which a first interface connection port is provided at one end of the memory card, and a second interface port is installed at the other end opposite. The protective cover also includes a case and a cover, the case providing a space for accommodating the memory card. However, the second interface connection port of the memory card is exposed to the outside of the case, and a correction spacer is formed at one edge of the opening of the case to the outside so that the correction spacer is properly positioned at the bottom of the second interface connection port of the memory card. By adjusting the thickness of the second interface connection port, the thickness of the second interface connection port is adjusted to meet the specification of the interface connector installed in the read / write device.

As can be seen from the above patent, the second interface connection port refers to a USB jack, and if the thickness of the second interface connection port is corrected by using a correction spacer on the protective cover, the USB jack meets the basic standard, and furthermore, read-write. Fully matched to the interface connectors specified in the device, a stable mating relationship can be achieved. Since the structure is simple, simple and practical, a patent was obtained (Invention Patent No. 1249884).

Accordingly, a main object of the present invention is to provide a memory card capable of automatically correcting a kind of interface standard, and mainly performs thickness correction on a communication interface port installed at one end thereof using a correction mechanism built in the memory card. Thus, when the communication interface port is inserted into the interface connector on the read / write device, the memory card is made to completely conform to the specification of the interface connector to achieve a stable bonding relationship.

The main technical means taken to achieve the above object include the following in the memory card.

A contact is provided, and at least one elastic member is installed below the support block inside the housing. The elastic member is supported between the support block and the inner bottom of the housing, through which the conductive contact of the support block can rise to an appropriate height.

The correction mechanism forms a plurality of through grooves on the first surface or the second surface adjacent to the second end of the housing, and installs one metal piece in each through groove to form a conductive contact of the communication interface port. Moreover, the said correction mechanism is comprised by the carbon piece respectively provided in at least one end of each said metal piece. Each piece of carbon provides elasticity to the metal pieces while supporting between the inner bottom surfaces of the housing. In the normal state, each piece of metal is pushed out of the through groove to be positioned at an appropriate height so as to be matched with a corresponding interface connector. Each piece of metal can also be compressed and deflected into the housing.

A plurality of through grooves are formed in a first surface or a second surface adjacent to the second end of the housing, and metal pieces are installed in the respective through grooves to form conductive contacts of the communication interface ports. In addition, the correction mechanism is composed of an elastic member which is installed under each of the metal pieces, the elastic member supports between the metal piece and the inner bottom of the housing, so that the metal piece is located at a suitable height while being pushed out of the through groove when the metal piece is in a normal state Match with the corresponding interface connector.

The present invention can be applied to a memory card having various extended communication interface ports other than the existing interface port, and for the sake of understanding, the following embodiment will describe the MS DUO card as an implementation target, which is one possible embodiment. It is merely to be noted that the present invention is not intended to limit the application target of the present invention.

The MS DUO memory card shown in FIGS. 1 and 2 is provided with one standard interface port 11 at one end of one of the flat housings 10 and the other end of the same or opposite side. One communication interface port 12 is installed. In the present embodiment, the communication interface port 12 is a USB interface port, taking only the structure of the electrical connection portion of the standard interface port. In other words, a plurality of terminals are provided in one insulation plate. Under the above circumstances, in order for the thickness of the communication interface port 12 to comply with the standard specification of the MS DUO memory card, the communication interface port 12 is formed in the memory card housing because the width of the USB interface port is smaller than that of the MS DUO memory card. (10) It shall be located at the center or side of the rear end. In this embodiment, the communication interface port 12 is located at the center of the memory card housing 10. Since the MS DUO memory card has standard dimensions, even if the communication interface port 12 is expanded, it still conforms to the original standard, and the communication interface port 12 uses the space behind the housing 10, so that the length is MS. Even if it conforms to the standard specifications of the DUO memory card, the rear end of the housing 10 thus forms an open groove, so that the memory card 10 also has a sliding cover that is also flat in order to be fully conformed to the dimensional specifications of the MS DUO memory card. Covering the (20), the height / width of the sliding cover 20 is close to one end of the standard interface port 11 installed in the housing (10). The sliding cover 20 is slid from the intermediate position of the housing 10 to one end of the communication interface port 12 is installed to correct the width of the end, so as to be close to the one end provided with the standard interface port 11, Appearance dimensions of the housing 10 are close to the standard specification of the memory card. When the communication interface port 12 is used to connect with the read / write device, when the sliding cover 20 is pushed back, the communication interface port 12 is exposed to insert and connect with the read-write device.

The above description is the basic structure of the present invention, and the main technical feature of the present invention is to correct the standard difference between the communication interface port 12 and the standard USB jack.

Since the communication interface port 12 belonging to the USB interface is integrated in the memory card, for example, the MS DUO memory card has a standard thickness of 1.6 mm, but the thickness of the USB jack (only the insulating plate portion) is about 2.0 mm. In between, there is a drop of about 0.4 mm. Due to this difference in thickness, when the communication interface port 12 is inserted into the USB interface port connector, it is easy to loosen because there is a gap, and may even affect the normal transmission of data. Therefore, the present invention is to install a correction mechanism in the portion corresponding to the communication interface port 12 in the housing 10, so that when the communication interface port 12 is used to automatically correct the thickness difference It was. Specific technical details and various possible embodiments will be described in detail below.

EXAMPLE

First, referring to FIGS. 1 to 5, the detailed structure and operation method of the first preferred embodiment of the present invention are shown. Referring to FIG. 3, one circuit module 30 is provided in the housing 10 of the memory card. ) And one correction mechanism (not shown) are installed, that is, one sliding cover 20 is installed outside.

The housing 10 is of a flat shape and has a first end 101 and a corresponding second end 102 and consists of a first / second housing body 13/14 combined with each other. Among them, the outer surface of the first housing body 13 is a first surface, and the outer surface of the second housing body 14 is a second surface. Among the first surface, a plurality of grooves 131 are formed at the edge portion adjacent to the first end 101, and the second surface is provided with the communication interface port 12 at the second end 102. do. In this embodiment, the communication interface port 12 is composed of a plurality of conductive contacts 120, each conductive contact 120 is electrically connected to the circuit module 30.

The circuit module 30 is installed inside the housing 10, a memory and related circuits are installed on a circuit board, and a plurality of metal contacts are installed at one end thereof, and each metal contact (not shown) is installed on the circuit board. The standard interface port 11 is configured by being positioned corresponding to the inside of each groove 131 on the first housing body 13 of the housing 10.

The correction mechanism is located inside the housing 10 and located on the second end 102 and corresponds to the communication interface port 12 thereon. In the present embodiment, the correction mechanism has an opening 141 formed at a portion adjacent to the second end 102 of the second housing main body 14, so that one support block is formed inside the opening 141. 15 is installed, one or more springs 16 are installed below the support block (15).

Among them, the size of the support block 15 is matched with the opening 141 so that the support block 15 can be installed therebetween, and one continuous edge around the lower edge of the support block 15 is directed outward. Edge 150 is formed. The edge 150 is larger than the opening 141, and the supporting block 15 is restricted in the opening 14 by the edge 150 to prevent the housing block 15 from being completely detached from the housing 10. In addition, a conductive contact 120 serving as the communication interface port 12 is formed on an upper surface of the support block 15.

In addition, the spring 16 supports between the support block 15 and the inner bottom surface of the housing 10, and uses the support elasticity of the spring 16 to push the support block 15 out of the second surface. This means that the conductive contact 120 thereon is also pushed up to an appropriate height (as shown in FIG. 4). In this manner, the housing 10 of the memory card is corrected in thickness of the second end 102 having the communication interface port 12, so as to be mated with the corresponding interface connector, thereby obtaining a stable insertion connection effect.

Since the memory card has an extended communication interface port 12 at one end, the width of the second end 102 of the housing 10 is smaller than the first end 101 in order to meet the USB interface standard. When inserting and connecting a read / write device using the standard interface port 11, the sliding cover 20 may be used to reduce the memory card to a standard standard. The sliding cover 20 may be formed of a metal or plastic material. The inner width / inner height is made to fit the Π-shaped cross-section frame of the housing 10, and it is fitted to the housing 10 by forming one clamping portion 21 inward in the horizontal direction at the bottom of each side wall thereof, respectively. For convenience, one end of the sliding cover 20 is made open, the other end is made closed, and one open groove 22 is formed at the closed end. The position and shape of the open groove 22 may coincide with the second end 102 of the housing 10 so that the communication interface port 12 on the second end 102 penetrates into the open groove 22. Make sure

In order to allow the sliding cover 20 to be installed as closely as possible to the housing 10, grooves corresponding to the shape of the sliding cover 20 are formed on the first and second surfaces thereof, and the width and thickness thereof are defined by the housing ( It manufactures to fit the 2nd stage 12 of 10).

When connecting the memory card to the read / write device using the standard interface port 11, the sliding cover 20 is pushed to the second end 102 of the housing 10 as described above (as shown in FIG. 2). When the width of the second stage 102 is corrected to be the same as the first stage 101, the memory card has a perfect appearance. In order for the sliding cover 20 to pass through the supporting block 15 on the second end 102, the supporting block 15 has one inclined surface 151 at a corner portion opposed to the traveling direction of the sliding cover 20. And the support block 15 is smoothly pressed against the housing 20 as the front edge of the sliding cover 20 passes through the sliding cover 20 along the inclined surface 151 (as shown in FIG. 5). In this case, the spring 16 below the support block 15 is in a compressed state, and when the sliding cover 20 is pushed out of the support block 15, the support block 15 is formed of the spring 16. It is pushed up using the resilient elasticity (as shown in FIG. 1).

6 to 9, as a second preferred embodiment of the present invention, the basic structure thereof is substantially the same as the first preferred embodiment, and the difference lies in the changed design of the correction mechanism.

The present embodiment differs from the above embodiment in that the conductive contact 120 of the communication interface port 12 is formed directly on the first surface of the housing 10. In the correction mechanism, one opening 141 is formed at a portion adjacent to the second end 102 in the second housing body 14, and one support block 17 is installed inside the opening 141. In addition, one or more springs 16 are installed below the brace block 17.

Among them, the dimension of the bracing block 17 is matched with the opening 141 so as to penetrate between the openings 14, and also to the outside at the edge below the bracing block 17. A continuous border 170 is formed. The edge 170 is larger than the opening 141, and the brace block 17 is limited in the opening 141 by the edge 170, thereby preventing it from being completely detached from the housing 10. In addition, the bracing block 17 is formed with one inclined surface 171 at a corner portion of the sliding cover 20 opposite to the advancing direction, when the sliding cover 20 is pushed to the second end 102, the bracing block Make it easy to pass (17).

In addition, the spring 16 supports between the bracing block 17 and the inner bottom surface of the housing 10, and uses the support elasticity of the spring 16 to push the bracing block 17 out of the second surface. This means that the conductive contact 120 thereon is also pushed up to an appropriate height (as shown in FIG. 8). In this manner, the housing 10 of the memory card is corrected in thickness of the second end 102 having the communication interface port 12, so that the housing 10 of the memory card is fitted with the corresponding interface connector, thereby obtaining a stable insertion connection effect. .

As in the above embodiment, when the sliding cover 20 is pushed to the second end 102 of the housing 10, the width of the second end 102 is corrected to be equal to or close to the first end 101. . At the same time, the brace block 17 is also pushed back by the sliding cover 20 into the housing 10 (as shown in Figure 9).

10 to 13, as a third preferred embodiment of the present invention, the basic structure is largely the same as the first preferred embodiment, the difference is still in the changed design of the correction mechanism.

In the present embodiment, the housing 10 has a plurality of through grooves 142 in the form of a strip is formed in the second housing body 14 adjacent to the second end, each one inside each through groove 142 A metal piece 121 is installed to form a conductive contact 120 of the communication interface port 12. The metal piece has an approximately U-shape shape, and both ends thereof are positioned below the through groove 132 and are blocked by the groove edge of the through groove 142, and the protruding portion in the middle thereof is exposed between the through grooves 142. do. In addition, the correction mechanism is composed of coal pieces 122 which are respectively installed on at least one end of each of the metal pieces 121, in the present embodiment, the coal pieces 122 have a U-shape, the upper and lower arm portion of the housing ( While supporting between the inner bottom surface opposite to 10, it is electrically connected to the circuit module (30). The bullet piece 122 provides elasticity that the metal piece 121 can stretch and contract in the through groove 142, so that each metal piece 121 is pushed out of the through groove 142 in a normal state and positioned at an appropriate height. To compensate for the insufficient thickness of the communication interface port 12.

Since the metal pieces 121 in the through grooves 142 have a U-shape, one inclined surface is formed at one end of the sliding cover 20 opposite to the moving direction, so that the sliding cover 20 is advantageously passed. When the sliding cover 20 is located above each metal piece 121, the metal pieces 121 are simultaneously pressed back into the housing 10, and the one end of the bullet pieces 122 is also compressed at the same time (Fig. 13). As shown in).

14 to 17, as a fourth preferred embodiment of the present invention, the structure is very similar to the third preferred embodiment, but the difference is still in the modified design of the correction mechanism.

In the present embodiment, the housing 10 has a plurality of strip-shaped through grooves 142 formed at a portion adjacent to the second end 102 of the second housing body 14, and each through groove 142. One metal piece 121 is installed inside each of the conductive contacts 120 of the communication interface port 12. The metal piece has an approximately U-shape, and both ends thereof are positioned below the through grooves 142 and are blocked by the groove edges of the through grooves 142, and the intermediate protrusions thereof are exposed between the through grooves 142. .

In addition, the correction mechanism is composed of a spring 16 which is installed under each of the metal pieces 121, each metal piece 121 is electrically connected to a circuit module (not shown) through the spring 16, The spring 16 is supported between the metal piece 121 and the inner bottom surface of the housing 10 to provide elasticity that the metal piece 121 can stretch and contract inside the through groove 142. In the normal state, each metal piece 121 is positioned outside of the through groove 142 and supported at a suitable height under the support of the spring 16, and likewise corrects the insufficient portion of the thickness of the communication interface port 12. Get

Since the metal piece 121 inside the through groove 142 has a U-shape, one end opposed to the moving direction of the sliding cover 20 also constitutes one inclined surface so that the sliding cover 20 is advantageously passed. In addition, when the sliding cover 20 is pushed upward over each metal piece 121, each metal piece 121 is simultaneously pressed into the housing 10. At this time, the spring 16 under the metal piece 121 is in a compressed state (as shown in FIG. 17).

As can be seen from the above description, the present invention mainly installs a thickness correction mechanism in a portion corresponding to the communication interface port in the memory card to automatically correct the thickness of the communication interface port portion of the memory card, thereby providing a memory card. Inserting the communication interface port into the corresponding interface connector on the read / write device ensures a stable coupling effect while perfectly conforming to the dimension specification of the interface connector. The technology is, for example, CF ™ card, SD Memory Card, miniSD ™ Card, microSD ™ card, MMC card, MMCplus ™ Card, MMCmobile ™ Card, MMC micro ™ Card, Memory Stick, Memory Stick PRO, Memory Stick Duo, Memory It can be applied to various memory cards such as Stick PRO Duo, Memory Stick Micro, xD-picture ™ Cards or T-Flash.
